Nyrux Hi, I plan to use Hetzner's external firewall. Optionally with a network. Anything to keep in mind? Or tips and experiences? I would be very grateful to you.
cosmoshosting Works good. Use groups. Like when working with Firewalls for any enhance system Whitelist the IP's of each of the other Enhance servers Whitelist any static IP of your office or VPN Consider what ports you want open on each server (if you don't use FTP, don't expose it) Be sure to consider both ipv4 and ipv6 in your firewall rules If you plan to send emails, be sure to enable port 25 for both outgoing and incoming Lastly Always validate your firewall rules, you can download nmap and run it from your own computer or use online port scanning tools.
